Abstract
To solve a problem due to a transient regulation phenomenon (6) at the time of an increase in power demand (1) in a mobile telephone, the regulator is pre-compensated (7) at a time (T′) in advance of a predicted time (T) of the increase in electrical power demand in the mobile telephone. As a result, a power supply voltage (Vr) crossing an operating threshold (3) outside a period of use has no harmful effect on the operation of the mobile appliance.
